Reasons for the failure of the hydraulic cylinder of the hydraulic press

The phenomenon of hydraulic press is different from the crawling phenomenon of hydraulic cylinder. After the signal is issued, the hydraulic cylinder does not move immediately, and then moves after a short pause, or sometimes it can move, and sometimes it stops for a long time, which is very irregular. The reasons for this insensitivity and the methods of elimination are mainly as follows.
①Excessive air removal method in the hydraulic cylinder of the hydraulic press: exhaust through the exhaust valve; check whether the air is inhaled by the sealing ring of the reciprocating part of the piston rod, and replace the sealing ring.
②There are irregularities in the operation of the hydraulic pump, such as large vibration and noise, severe pressure fluctuations, block rotation of the pump, and slight seizure.
③ The hydraulic cylinder of the hydraulic press has a buffer device. When starting in reverse, the orifice of the one-way valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs. Therefore, when the buffer plunger leaves the end cover, it will cause the piston to momentarily stop or reverse phenomenon. Remedy: increase the check valve orifice.
④When the piston moves at a high speed, the steel ball of the one-way valve flows with the oil flow, so that the valve hole is blocked and the action is irregular. Remedy: When the passing flow is large, it should be changed to a cone valve structure with a guide shoulder.
⑤ The inner layer of the rubber hose is peeled off, so that the oil circuit is open and closed at times, resulting in irregular movements of the hydraulic cylinder. Remedy: Replace the rubber hose.
⑥ The hydraulic press has a certain lateral load.
